The victim of the robbery said he met the suspect, who was wearing a Taco Bell employee shirt, on a bus ride downtown. Police say the suspect was "supposed to show the victim where he could catch a different bus to his next destination."

Both the suspect and victim got off the bus near downtown. On the way to the next stop, the suspect pulled out a handgun and demanded the victim hand over their backpack, officials said.

The suspect then punched the victim several times before fleeing with the bag, authorities said.

Crime Stoppers may pay up to $5,000 for information that leads to the arrest of the suspect responsible for the armed robbery. Anyone with such information is asked to call Crime Stoppers at 210-224-7867.
